I have been searching and reading for many many months. I was looking for the survival stats on Oropharyngeal cancer. Specifically, locally advanced (stage 4-lymph node involvement but not metastasized to other organs-stays above the neck). HPV negative and 30+ pack years.

My oncologist says 70% 5-year survival rate. My research shows only about a 40% (less than 50%) 3-year survival rate and a worse 5-year rate.

Overall, not figuring in HPV status, pack years and the fact of it is locally advanced stage 4 (lymph node involvement on one side of neck, my doctor is correct (really lying by ommission because I asked him "what about......" and he did not respond.

Am I on track with this. Just what to know the true stats on my disease. Thank you.
